Poly (lactic-co-glycolic acid) (PLGA) porous scaffold for tissue engineering. The patients own cells are seeded onto the scaffold and allowed to attach and start producing new bone. The construct is implanted into the defect site, where eventually the polymer will biodegrade and be completely removed, leaving a natural autogenous bone graft. This technique is particularly useful for large defects, or where the host bed is compromised due to disease, although it is still at the research stage. Average Pore Size 350-550 micrometre, porosity estimated at 35-45%.Author(s): DoITPoMS, University of Cambridge,V A Mellon, Depa

The Arts in Every Classroom: Creating a Multi-Arts Performance Piece Learner Team members and students examine the elements of the classic journey as identified by Joseph Campbell. They then create a multi-arts performance piece that represents a journey story. They apply what they have learned in previous lessons in order to rehearse, critique, revise, and perform their work.Author(s): No creator set

That proteins contain functionally and physically discrete modules or domains is an important principle, one that will be reinforced as we examine the roles of specific proteins in a variety of different cellular processes.

There are several advantages conferred by multidomain protein architecture:

Creation of catalytic or substrate-binding sites These sites are often formed at the interface between two domains, typically a cleft. Movement

The first alternative measure of dispersion we shall discuss is the interquartile range: this is the difference between summary measures known as the lower and upper quartiles. The quartiles are simple in concept: if the median is regarded as the middle data point, so that it splits the data in half, the quartiles similarly split the data into quarters. This is, of course, an over-simplification. With an even number of data points, the median is defined to be the average of the middle two: de

"On a basic level, a job is the result of the mixing of capital and labor."

Why can't everyone who wants a job, or a better job, just find one? In a perfect world, this would be the case. Sadly, the recently released employment figures for June indicate that the world in which we live is still far from perfect.

Finding the Hypotenuse The hypotenuse of a right triangle is the side that is opposite of its right angle. Sometimes we have problems that ask us to find the missing hypotenuse of a right triangle. This video describes how to use the Pythagorean theorem to find the hypotenuse, but only when the length measure of the two legs is known. (1:16)Author(s): No creator set

Under fuel-lean conditions (excess O2), the oxidation of CO has been studied over a very large range of single crystals and model noble metal catalysts, one of the most intensively investigated examples being the Pd(111) surface. Although this metal is not a component of the current three-way catalyst used in the UK, it is worth considering the results in some detail for a number of reasons. The reaction on metals such as Pt is in many ways similar to that on Pd and, in any
